Huh, interesting. I think I recall running into that one also, but not consistently. The mis-match with GP usage are deeper than re-gendering the name though. Seems to me Mary Sue/Gary Stu is fundamentally about projection/wish fulfillment on the part of author (or in this case, player?), and has no real opinion on gender roles/relations/etc. GP seems to be adding a bunch of that; I’ve no opinion on whether or not the text (game) supports that take, but seems a bit orthogonal to the Mary Sue concept.
